I know this is getting pretty old by now with people asking why their Arduinos are not communicating correctly with their computers via USB ports.

Anyways, I can't find a solution to my problem via Google or the troubleshooting guide (Unless I am not looking correctly through the guide, will keep reading through though). My problem is the IDE sees COM1 and it is selected. I opened up my device manager (using windows 7 64-bit) and installed all the correct drivers, or at least I think I did, also the strange thing is my computer, when the Uno is connected, does not show "Arduino UNO (COMxx)" but instead it just shows "Communications Port" under the "(COM & LPT)" selection. I also have a ton of USB ports, at least 10, so I tried plugging my Arduino in each one and nothing happens. The error I get in the IDE is "avrdude: stk500_getsync(): not in sync: resp=0x00".

Does anyone have any ideas?

Update - I just found out that in my device manager under "other devices" my arduino is identified as "Unknown Device". When I unplug it, it goes away. When I plug it back up it comes up as "Unknown Device".
